Scott Pelley is out at “CBS Evening News,” Page Six has exclusively learned.

Sources tell us that “Poison Pelley’s” office was being cleared out Tuesday while the anchor was away on an assignment for the network’s news magazine “60 Minutes.”

We’re told he’s being shifted permanently to “60 Minutes.”

Insiders tell us that CBS News president David Rhodes “is making [Pelley] move to ‘60 Minutes,’ ” and that the pair “don’t get on.”

Another TV insider said that while Pelley’s ratings have been down, “There’s also been friction between him and [Rhodes].”

Added a source, “[Pelley] was pushed out of the ‘Evening News.’ It’s been coming for a long time. This could have been handled better — [Pelley] is away on a story, and they’re cleaning out his office. It’s not the correct way to treat the face of CBS News.”

No replacement has yet been named, but CBS has a deep bench of anchors who can fill in.

Sources say there was confusion Tuesday among staff at CBS’ Hell’s Kitchen headquarters as workers began dismantling the office of Pelley — dubbed “Poison Pelley” by Page Six after he yelled at a reporter in 2013, “You wouldn’t last 10 seconds at CBS News!”

Others insist Pelley is moving to the “60 Minutes” offices.

We reported in December that Pelley was on his way out of the anchor chair on the flagship news show — where he has sat since he succeeded Katie Couric in 2011.

At the time, the network denied the story, telling us, “There’s no truth to this.”
